Aquaflair DF

Flexible chillers for installation where the airflow must be ducted

Ducted chillers are designed to offer a complete solution for mission critical installations where the conditions do not permit a traditional axial fan chiller selection. Thanks to the high external static pressure fans, these chillers have the flexibility to be mounted in various building locations located either indoors or outdoors. All of Schneider Electric's Aquaflair Chillers offer low noise impact through the use of large air side exchangers, controlling fan rotation, and compressor insulation and housing. Our advanced controls system constantly monitors set points to guarantee the unit always operates within operating limits and will signal any faults before breakdown occurs. These chillers support a wide range of applications and maximize the availability of Row and Room cooling products to provide a complete heat removal solution.

Allows for all serviceable components to be replaced/maintained by easily accessible panels/doors.

Operational Service

Allows critical components to be maintained/replaced while the system is in operation.

Service monitoring

All the monitoring devices on board the unit allow for preventive maintenance and a check of the working condition of the system while its in operation.

Total Cost of Ownership

Integrated Hydronics Package

Includes all the necessary components to make one connection to the chilller without the need of external connections to auxiliary equipment such as pumps, increasing the speed of deployment.

Modular strategy

Modular design of the mechanical and control systems allow for gradual build-up of the cooling infrastructure to match the cooling demand of the facility. This greatly reduces CAPEX expeditures and provides deferred investment throughout the life of the facility.

Integrated pumps adjustment system

(Optional) VSD onboard pumps are available for continuous adjustment of the chilled water loop available pressure. This provides automatic adjustments in Chilled water flow due to changes in cooling demand which ensures efficiency of the chilled water system.

Monitors and actively adjusts cooling capacity to ensure proper server inlet temperatures. Through the microprocessor controller, visibility into the operation and status of the unit is provided.

Separate power input

Draws power from the external UPS for mainboards and heaters to monitor and protect the unit even in complete power failure mode (optional)

Quick restart

Full load operation in less than 3 minutes with specific arrangements permits undersizing of the storage tanks

Compressors

Scroll and screw compressors utilize few moving parts for increased reliability and life expectancy

Redundant Components

Single points of failure in the system have redundant compononents to maintain availability and reliability.

Sizing and run time calculators are based on Watt ratings. VA (Volt-Amp) ratings are also a common method for measuring power but provide less accurate results. On APC.COM, VA values are often shown for convienience and may be entered as input data. However, VA values are always translated into Watts. This translation is done using an approximation formula which assumes that low VA loads have a power factor of around 0.6 and high power loads have a power factor of nearly 1.0, which is representative of typical, (but not all) computing equipment. For highest precision, use Watt values where available.

The translator below shows how VA can be converted to Watts using the APC.COM formula:
